The Study of a New Modified Bicanalicular Intubation for the Repairment of Traumatic Canalicular Laceration

INTRODUCTION: To investigate the efficacy and safety of a modified bicanalicular intubation (MBCI) used in canalicular laceration. MATERIALS AND METHODS: This study is a retrospective consecutive chart review. A total of 43 eyes from 43 patients (36 males and 7 females) who underwent canalicular intubation were enrolled. Success rate was determined at 6 months after the surgery. Anatomical success was determined by diagnostic probing and irrigation; functional success was determined by asking patients about tearing. RESULTS: Irrigation of the lacrimal passages in all 43 eyes showed that they were free from obstruction. The anatomical success was 100%, and 37 eyes (86%) achieved functional success. 6 eyes (14%) could not achieve functional success because there were some residual symptoms under irritating conditions, such as wind or winter weather, among which 2 eyes had bicanalicular lacerations and 4 eyes had lower canalicular laceration before surgery. There were no other complications observed in this study. CONCLUSIONS: The MBCI was simple and safe for using in canalicular laceration.
